LIQUID-DISPENSING APPARATUS.

Application filed February 18, 1920. Serial No. 359,193.

, Apparatus, of'which the following is a specification.

Our present invention hasfor its primary object the production of an improved liquid dispensing apparatus particularly adapted for dispensing gasoline.

Another object of the invention is the production of a gasoline dispensing apparatus or motor-vehicle filling-station, enibodying a plurality of gasoline containers, and so constructed and associated that while one container is being drained another is being filled.

Furthermore the invention contemplates a gasoline filling-station embodying a plu rality of gasoline containers, quantityindicatingmeans for the respective containers and valve mechanism constructed and arranged that while a container is being drained, an empty container is being filled.

Still a further object ofthe invention is the production of a gasoline filling station comparatively simple and inexpensive in construction, yet durable, dependable and thoroughly efiicient 'in operation.

These and other objects we successfully attain in the embodiment hereinafter de scribed, defined in the appen'dedclaims and illustrated" in the accompanying drawing; which form apart of this application and in which like cha'ractersof reference indicate corresponding parts throughout the constructed in accordance with the inven Specification of Letters Patent.

Patented Mar. 7,1922",

Fig.6 is a plan of one of thevalve connecting links and associated fragmentarily; and i Fig. -7 is a side elevation thereof. While we have illustrated and hereinafter described the preferred embodiment of the invention, we; would not be understood as belng limited to such specific construction,

parts shown for various alterations and modifications may be made in the details of construction and arrangement of the parts describedf Without departing from the spirit and scope,

of the invention, as defined in the appended claims.

Referring, now, to the illustrations, the device consists, preferably, of acylihdrical jacket of upper and lower parts,v8- and 9 respectively, the part, 9, being mounted on a-sultable support, as a base ring, 10, having a flange, 11, which is encircled by the acket portion, 9. Upon the upper end'of the jacket portion, 9, rests aplate, 12, hav. ng an annular flange, 13, engaging the lnner periphery ofthe jacket portion .5). Upon the plate, 12, rests the jacket portioin 8, held in axial alinement with the lower jacket portion. by a flange, 1 1 on the plate, 12. The jacket is covered by a dome, 15, having aflange, 16, encircled by the jacket,

and formed with inner lugs, '17, through which pass tie-rods, 18, which depend tl'irough the plate, 12, and are suitably se cured as at 19, to the base ring to securely fix the jacket, its cover, plate 12, and base 10, againstrelative movement.

The jacket portion, 8, encloses two con:- tainers or tanks, 20 and 21, supported side. by side upon' the plate, 12. The front of the jacket portion, 8, is provided with an opening, 22, enclosing an upright strip, 23, having grooves, 24:, enclosing gaugeglasses, 25, the lower ends. of which communicate. with the respective tanks, through suitable ducts, 26; and theface of the strip, 23, be-

tween the grooves is graduated as at, 27, in suitable units of liquid measure. Within the gauge glasses, 25, are floats, 28, prefe erably bright colored, rendering, them readily visible; Thus, the, gasoline maintains the same level in the gauges as in the tanks, and the quantity of gasoline in either tank is readily determined by the position of the associated float with respect to the adjacent scale, 27.

The bottom of each of the tanks, 20 and 21, is provided with a suitable inlet valve, 30, and an outlet valve, 81. The inlet valves of the two tanks are interconnected by a manifold or pipe, 32, with a pipe, 33, adapted to be connected with a suitable source of gasoline pressure; and the valves, 31, are similarly interconnected by a manifold or pipe, 34, with an outlet pipe, communiczding with a flexible duct or hose, 36, extend ing through an opening, 37, in the jacket portion, 9. The valves are provided with horizontally oscillating controlling arms, 38, which normally are rearwardly swung as shown in full lines in Fig. 4.

When the valve are closed the valves, 30, are heldyieldably closed as by retracting springs, 39, secured to the arms, 38, and the jacket, 9, and the valves, 31, may be held yieldably closed as by retracting springs, 40, secured to controlling arms, 38, and the tank-supporting member, 12.

To the outlet-valve cont-roiling-arms, 88, we secure rods, 41, respectively, the free ends of which protrude through openings, 42, in jacket portion, 9, and are provided with suitable handles, 43, for pulling the rods outwardly or forwardly. The inletvalve controlling-arm of each tank and the outlet-valve controlling-arm of the companion tank are so connected that they are opened in unison and permitted to close, each independently, from the other, whereby one tank, if empty or partially empty, will be filling while the other is being drained, and when the one is properly filled, means are provided for automatically closing its inletvalve while the other tank still be draining. F or this purpose we interconnect the inlet-valve controllingarm of each tank with the outlet-valve controlling-arm ofthe other tank by a rod or other suitable link, 44. The induction-valve controllingarms are provided with swivel heads, 45, through which pass reduced portions, 46, of the associated rods, 44, provided on their rear ends with bosses, 47 engageable with the heads, 45, to swing the adjacent valve-- controlling-arms forwardly, as presently Wlll appear. The said rods are held yieldably rearwardly as by retracting springs,

48, secured to the rods and the jacket portion, 9. The eduction-valvecontrollingarms, 38, are provided with suitable heads, 49, having slots, 50, in which the associated rods, 44, are free to slide. In the underside of the arms, 44, are/ notches, 51, which normally so engage the heads, 49, that when the rods, 44, are drawn forwardly, similar motion is imparted to'the associated controlling arms.f3c, a 7

Now, itwill be observed, when one of the rods, 41, is drawn forwardly the outlet-valve controlling-arm, 38, therewith connected, and the associated inlet-valve controllingarm will both be drawn forwardly to open their valves.

The inletwalves are held open when their controlling-arms are swung forwardly by means of float-controlled latch mechanism, which includes horizontal arms, 52, which intersect the sweep of the said controlling arms and have one end pivoted to suitable bearings, 53, mounted on the supporting element, 12, and their free ends are pivoted to the lower ends of rods, 54, the opposite ends of which are pivoted to the intermediate portions of arms, 55, having one end pivoted to suitable bearings, 56, on the superstructure and carrying at their free ends depending rods, 57 provided with floats, 58, within the respective tanks. The undersides of the arms, 52, are provided with notches, 59, en-

gageable with lugs, 60, on the inlet-valve controlling-arms, 38. Now, when one of the rods, 44, is moved forwardly, the associated induction-valve is held open by virtue of engagement of the notch, 59, in the adjacent latch arm, 52, with the lug, 60, and as the rod, 44, approaches its extreme forward position it engages a shoulder, 61 on the interior of the jacket, whereby the notched portion, 51, thereof is disengaged from the slotted head, 49, which permits the spring,

48, to retract and leave both valves open; then when the desired quantity of gasoline is drained from the tank the controlling rod, 41, is released permitting the eduction-valve controlling-arm to swing rearwardly and close its valve,- and as the float is raised by gasoline in the tank being filled, the latch arm, 52, is lifted through the medium of the associated rod, 54, to disengage the notched portion, 59, from the lug, 60, whereupon the induction valve immediately closes.

Having thus described our invention, what we claim as new and. desire to secure by Letters Patent of the United States is,

1. A liquid-dispenser embodying a' plurality of liquid containers, induction and eduction valves for each container, each valve including movable controlling means, connections between the eduction valve-controlling means of each container and the induction valve-controlling means of another container operable to open the connected valves simultaneously, and permit them to be closed independently, each from the other, and. float-controlledmeans operable to automatically close the induction valves.

2. A liquid-dispenser embodyingapair of uniform liquid containers, induction and eduction valves for each container, each valve including movable controlling means, a connection between the induction-valve controlling means of each container and the eduction-valve controlling means of the other container operable to open the 0011- nected Valves simultaneously and permit associated containers to hold their valves them to be closed independently, each from open.
